The Choquet-Deny convolution equation \(\mu =\mu *\sigma\) for probability measures on Abelian semigroups
The authors characterize the regular probability measures \(\mu\) satisfying the Choquet-Deny convolution equation \(\mu =\mu *\sigma\) on Abelian topological semigroups for a given probability measure \(\sigma\). The method of proof is the usual martingale argument given by many other authors.
